BUILDING CONSTRUCTIQN.

Application filed December 13, 1920.

T0 cZZ whom-id may concern:

it known that l. (Autos l1. Dnizrmno, a citizen of the Republic of SanSalvador,

residing at" San Salvador city, San Salvador, have invented certain newand useful Improvements in fiuilding Construction; and I do herebydeclare the following to be a full, clear, and exact description of theinvent n. such as will enable others skilled in the art to which itappertains to make and use the same.

The present invention relates to improvements in building constructions,and has for same principle as that of reinforced concrete I in whichmetal reinforcing bars or rods are used. The invention differs fromconcrete construction in that instead of pouring the concrete in situ tothe metallic rods I prefer to employ manufactured bricks or blocks ofconcrete, clay or other suitable material of peculiar form, which makesit possible to build walls of an interlocking and reinforced characterwhile dispensing with the difiicult and slow labor of passing metallicrods through holes inthe bricks or blocks used in other concretestructures.

In accordance with the above mentioned principles one can obtain one ormore forms of blocks from almost any simple geometri cal figure. But Twill limit my description the'present to the three main types of blocksderived from the rectangle.

The invention will be more fully understood after reference to theaccompanying drawings, in which like parts are indicated bycorresponding reference symbols throughout the various views, and inwhich z- Figure 1 is a fragmentary perspective view of a wall built upin accordance with the present invention.

Figure 2 is a plan view thereof.

view of a composite double wall construction; and

Figure 7 a perspectiveview of a column built with blocks, as shor-Jn inFigure 5.

Referring more particularly to the drawings, and for the present toFigure 3, there is herein shown concrete, or oth aopro ate material. itsform proceeds i a rectangle in plan, of which two squares have beentaken off from its two corners corresponding to one of its longer sides.lt comprises a body 1'. provided with a right angular extension 2profrom the central portion thereof, and at one side combining with thebody construction. In the edge of the body 1, opposite to the projection2, is provided a slot in which to receive a reinforcing metallic rod or'bar 4.

Figures 1 and 2 represent how blocks or bricks of the character shown inFigure 5 may be assembled to form a column at one end of a wallstructure. The blocks are laid in courses one above another andpreferably in pairs with the free edges of the projections 2 facing oneanother. The blocks alternate in direction from one course to another.The arrangement provides spaces 5 and 6 opposite sides of the pillow orcolumn in which to receive the end portions of the wall at one side andfiller blocks 7 atthe other side, which filler blocks are substantiallyrectangular in plane and are provided with slots 8 on their outer facesof substantially the shape and arrangement of the. previously describedslots 3.

Figure 1 shows how the spaces 5 and 6 alternate throughout the variouscourses. The wall itself is, according to one method, composed of bricksor blocks of the character illustrated in Figure 4:, in which 9 desinates generally the body of the brick or block which is also made ofconcrete, clay or any other suitable material. This block brick blockmade of 1 also possesses a generally rectangular con- The tips of andflattened, as indicated at 14, in order to lie against the reinforcingrods and combine with the slots 12 in order to effectively close thesame where they open into the re cesses ll. fit the bases of theprojections or tongues 10 the block 9 is provided with shoulders 15, andsimilar shoulders 16 disposed at the other end of said block outwardlythe flaring walls of the recess ill. The shoulders of adjacent blocksadapted to come together in the manner indicated in Figures and 2,

in assembling the wall the blocks 9 are laid in courses preferably withbreak joints. Filler blocks 17 are employed in conjunction with thecourses of the wall, and are of shorter length than the blocks 9 inorder that they may appropriately enter the spaces 5 in the columnconstruction. Slots 18 are likewise formed in the filler blocks 17 andtongues 19 are provided thereon to enter the recess 11 of an adjacentblock 9. The reinforcing rods 4i for holding the column together arefour in niunber, as shown in Figures 1 and 2, and are tied together by abinding wire 20 which is wrapped around each rod a suitable number oftimes, being then passed to the next rod and having the generalrectangular outline shown. A bind ing wire 21 is also wrapped about thereinforcing rods 13 in'order to space these rods at proper intervalsapart and reinforce the wall against longitudinal or lateral creeping. 7

It will thus be seen that a wall made in accordance with the abovedescribed invention provides a closely knit structure which will resistthe action of earth quakes and tend to remain in an integral conditionfor long periods of time.

In Figure 5 l showa further modification of block comprising a body 22having the general shape of a brick, but modified in that slots 23 and24 are made at opposite ends thereof, such slots projecting inwardly atright angles to the edges of the brick through which they open andextending substantially centrally thereof, coinciding substantially withthe longitudinal axis of the block. These slots 23 and 24 also receivereinforcing rods in the same manner as above indicated.

Referring to Figure 7, there is shown a pillar made up of blocks of thecharacter appearing in Figure 5. A pillar of this construction isprobably more appropriate for isolated columns and the rods and wiresare disposed similarly to the preceding figures.

In Figure 6 I have shown a more elaborate construction of wall involvingthe same principle as heretofore described in connection with Figures 1and 2, but in this case alternate courses of the'wall are made on theblocks 9, arranged in double rows side by with their projections facedalternately in opposite directions so that the shoulders 25 and 26 mayabut and form a strong and rigid structure. The wires also be usedbetween the courses and between adjacent Vert1cal reinforcing rods arealso blocks. employed in this construction lying within the slots 3 ofthe blocks 1 and in the notches 12 of the blocks 9."

lt will be appreciated from the foregoing that many modifications of theherein dis closed idea may be resorted to, and the various styles ofblocks shown in Figures 3, 4; and 5 may be united in various other waysto produce a wall strengthened and closely knit together by reinforcingrods, at the same time taking advantage the use of manufactured bricksor blocke'and dispensing with the troubles incident to the. pouring ofconcrete.

I claim: 1

1. A building construction comprising blocks laid horizontally incourses, blocks of certain courses having tongues extending from oneend, recesses to receive the tongues provided in the other ends thereof,the blocks of alternate courses being composed of body portions withright angular projections formed centrally thereof, and providingshoulders at opposite sides of the projections, said last mentionedblocks being laid in opposite directions successively whereby to engageadjacent shoulders, said last mentioned blocks also having slots thereinin alignment with the slots in the first mentioned blocks, andreinforcing rods passing vertically up through the slots in said blocks,substantially as described.

2. A building construction comprising blocks laid horizontally incourses, blocks of certain courses having tongues extending from oneend, recessesto receive the tongues provided in the other ends thereof,the blocks of alternate courses being composed of body portions withright angular projectionsformed centrally thereof, and providingshoulders at opposite sides of the projections, said last mentionedblocks being laid in opposite directions successively whereby to engageadjacent shoulders, said last mentioned bloc-ks also having slotstherein in alignment with the slots in thefirst mentioned blocks,reinforcing rods passing vertically up through the slots in said blocks,and horizontally disposed binding wires extending longitudinally betweencourses of blocks,
